# Java Math asin() Function

## Java Math Class

Java Math class provides several basic and advance methods to perform different operations on math calculations like max(), min(), sin(), round(), ceil(), floor(), asin() etc.
The java.lang.Math class contains various methods for performing basic numeric operations

Here, in the page we will discuss about the asin() Method in java.

## Java asin() Function :

Java Collection contains Math class and The class Math contains methods for performing basic and advance numeric operations such as the exponential, logarithm, square root, and trigonometric functions.
The Java asin() Function returns the arc sine of a given input. arc sine is also known as inverse of sine.
The given input should always be less than 1. if the given input is NaN or lesser than 1 then the output will be NaN.

#### Syntax:

`Math.asin(number);`

#### Return Type :

clear() Function in ArrayList

clone() Function in ArrayList

#### Example For Numbers in Valid Range:

Run
```import java.util.*;

public class Main{
public static void main(String[] args){
double a = 0;
double b = 0.1;
double c = 1;

// Printing asin value for 0
System.out.println("asin value of 0 is : " + Math.asin(a));

// Printing asin value for range between 0 and 1
System.out.println("asin value for number in range is : " + Math.asin(b));

// Printing asin value for 1
System.out.println("asin value for 1 is : " + Math.asin(c));
}
}```
```Output:

asin value of 0 is : 0.0
asin value for number in range is : 0.1001674211615598
asin value for 1 is : 1.5707963267948966```

In the above Example, We had taken examples for double values with range includes 0 to 1

#### Example for Out of Range Numbers:

Run
```import java.util.*;

public class Main{
public static void main(String[] args){
double a = 10;
double b = 2.5;
double c = 1.1;

// Printing asin values for out of range values
System.out.println(Math.asin(a));
System.out.println(Math.asin(b));
System.out.println(Math.asin(c));
}
}```
```Output:

NaN
NaN
NaN```

In the above Example, We had taken out of range numbers for which we will be getting NaN output.

#### Example for Negative and NaN Value Number :

Run
```import java.util.*;

public class Main{
public static void main(String[] args){
double a = -10;
double b = -2;

// Printing asin values for Negative Numbers
System.out.println(Math.asin(a));
System.out.println(Math.asin(b));
}
}```
```Output:

NaN
NaN```

In the above Example, We had taken negative value which gives NaN output.
